Giants' Prince Amukamara, Cooper Taylor suffer injuries

The Giants' secondary took two hits in Saturday's win over the Colts, with starting cornerback Prince Amukamara suffering a groin strain and second-year safety Cooper Taylor injuring the sesamoid bone in his left foot. Amukamara had an MRI Sunday night. Tom Coughlin said Taylor's injury is "significant" and will cause him to miss "quite a bit of time."

Coughlin said injured reserve has not been discussed regarding Taylor, but linebacker Jon Beason suffered a sesamoid fracture in the spring and his timetable for return was 12 weeks. If Taylor has a similar issue, that could sideline him until the middle of November.

As for Amukamara, the Giants replaced him Saturday night by moving slot corner Walter Thurmond III to the outside in two-cornerback looks. When the Giants had three corners, Thurmond was in the slot and Trumaine McBride was on the outside. The Giants also have Zack Bowman as a possible replacement for Amukamara if he has to miss time in the regular season.

"I definitely didn't hear anything pop," Amukamara said after the game. "I've had hamstring pulls and sometimes I thought I would be out for two weeks and then I'd be out for a week. This doesn't feel as bad, so I think we'll just see how it goes."

Robinson flashes

Adrien Robinson was born in Indianapolis almost 26 years ago. His career may have been born in the same city this weekend.

The third-year tight end finally showed the first glimpses of his ability with two key catches for 59 yards on the winning drive as the Giants beat the Colts, 27-26, on Saturday night. Ryan Nassib, who delivered the passes to Robinson, went so far as to say the tight end "saved" the Giants.

He may have saved his roster spot, too.

"I felt I definitely needed this, for sure, to prove that I should be on the field," Robinson said. "I guess you could say [there is pressure to] make the team. It's my third year. I need to go out there and make plays to stick around as long as I can."

Giant steps

Left tackle Charles Brown suffered a shoulder injury but had no structural damage and could be fitted for a brace to speed his return . . . Coughlin said the five jobs on the offensive line remain undetermined. "Just because five guys trot out there doesn't mean that's the starting unit," he said. He was pleased by the play of rookie Weston Richburg on Saturday . . . David Wilson's football career ended with a neck injury, but he still might have a future as an athlete -- in track. The former Giants running back told NBCSN's "Pro Football Talk" on Friday that he is considering the alternate sport. "I really like broadcasting, but on a different level, I want to compete and go back to track and compete in the triple jump," said Wilson, who was a national champion in the event in high school. "I think if I really focus, I can compete with the top-tier athletes in that event."
